Dark field autoradiograms comparing the effects of an excitotoxic lesions of the caudal hippocampus/entorhinal cortical area on the expression of glial fibrillary acidic protein (A) and PS-1 mRNA (B). Animals were sacrificed at either 3, 7, or 11 days postlesion. There was a marked loss of PS-1 mRNA within the bed of the lesion (arrows) after 7 days. This contrasts with the massive up-regulation of glial fibrillary acidic protein mRNA expression in adjacent sections.
